Overview
The aim of the study is to demonstrate non-inferiority of ANB-002 compared with preventive use of coagulation factor IX (FIX) in adult subjects with hemophilia B with FIX activity ≤2% and without FIX inhibitor. The study will have an open-label single-arm design.
Description
After signing the ICF and screening examination the subjects are to be included in the Non-interventional lead-in period in which the subject will receive standard FIX prevention. The lead-in period will last for at least 6 month for every subject.
After completiong the lead-in period subjects will enter the main (interventional) period.
At the first visit of the main period subjects will recieve investigational product ANB-002.
The main period ends 18 months after the administration of ANB-002, after which subjects will switch to the follow-up period and will be evaluated up to 5 years after the ANB-002 infusion.
